Human Gait Control Using Functional Electrical Stimulation Based on Controlling the Shank Dynamics
Introduction: Efficient gait control using Functional Electrical Stimulation (FES) is an open research problem. In this research, a new intermittent controller has been designed to control the human shank movement dynamics during gait. Methods: In this approach, first, the three-dimensional phase space was constructed using the human shank movement data recorded from the healthy subjects. Then...
متن کاملComparison of Agonist vs. Antagonist Stimulation on Triceps Surae Spasticity in Spinal Cord
Objectives: One of the most common and disabling complications that affects individuals with spinal cord injury is spasticity. The purpose of this study is to compare the effect of agonist and antagonist electrical stimulations on triceps surae muscle spasticity in patients with spinal cord injury. Methods: A total of 30 subjects with spinal cord injury were considered for the study. They were...
متن کاملNatural Control of Triceps Stimulation Using FES
Individuals with C5/C6 spinal cord injury have paralyzed elbow extensors, yet retain weak to strong voluntary control of elbow flexion and shoulder function. Previous studies have shown that functional electrical stimulation (FES) of the triceps provides sufficient elbow extension strength and control to greatly improve function. With triceps stimulation applied at a constant level, elbow angle...
متن کاملGait Event Detection during Stair Walking Using a Rate Gyroscope
Gyroscopes have been proposed as sensors for ambulatory gait analysis and functional electrical stimulation systems. These applications often require detection of the initial contact (IC) of the foot with the floor and/or final contact or foot off (FO) from the floor during outdoor walking. Previous investigations have reported the use of a single gyroscope placed on the shank for detection of ...
متن کاملDevelopment of calcaneal gait without prior triceps surae lengthening: an examination of predictive factors.
BACKGROUND Although equinus is more common in cerebral palsy (CP), the prevalence of calcaneal gait (CG) has been reported at more than 30% among patients with CP, even in the absence of prior surgical intervention. The goal of this study was to identify patient characteristics predictive of the development of CG in patients without prior triceps surae lengthening. METHODS Gait data were revi...
